Why are geometric blocks so expensive

Why are geometric blocks so expensive: 1, manufacturing cost is expensive. Building blocks can do the first and the first million of the error is basically zero, the drawings allow a tolerance of 0.002 mm, but also to ensure that the finished product basically can not see the mold line, such molds will determine the cost of building blocks is very high.

2, to ensure the accuracy of the finished product size, which leads to the number of cavities in each set of mold must not be more, so to meet the output, then you need a lot of sets of mold.

3, all blocks are processed with high standard specific ABS plastic as the main raw material, these raw materials not only meet the safety standards of toy grade, and even meet the standards of food packaging grade.

4, the sorting system is expensive. The use of high-precision automated sorting to ensure that leakage does not happen.
